在安卓游戏零星滞后 [英] Sporadic lag in Android game
问题描述
我正在用一个简单的Java的Android游戏。我注意到一些恼人的滞后每20-40秒。首先，我想他们我们被垃圾收集器造成的，但我检查了我的LogCat中我看到，有没有垃圾收集在游戏滞后时间。
标志着我的日志每次比赛begans落后，看到有几乎每次该日志条目：
I'm making a simple Android game with Java. I noticed some annoying lags every 20-40 seconds. First I thought they we're caused by the Garbage Collector, but as I checked my LogCat I saw that there's no Garbage Collection at the time the game lags. I marked the log everytime the game begans to lag and saw that there's almost everytime this log entry:
W / qdhwcomposer（209）：过多的延迟阅读VSYNC：把47毫秒
W/qdhwcomposer(209): Excessive delay reading vsync: took 47 ms
，因为它说，有一个延迟时间（通常> 45ms），我认为这就是我看到的滞后。
有谁知道这个问题，或者如何避免这些延误？
As it says, there is a delay (usually >45ms) and i think that's what I notice as lag. Does anybody know this problem or how to avoid those delays?
